Enabled dual camera (Raspberry pi 5)

When you can only see one of both cameras:

rpicam-hello --list-cameras

sudo apt update
sudo apt upgrade
sudo nano /boot/config.txt

set camera_auto_detect = 0

and depending on your situation, se the correct dtoverlay to your cam module

camera_auto_detect=0
dtoverlay=ov5647,cam0
dtoverlay=imx219

 

sudo reboot
